Answer:
0,218 moles
Explanation:
I will first explain how many liters is 256ml, that is 0,256 l.
because the m stands for milli which is a factor of 1000 -> (256 ml / 1000 = 0,256 l)
To calculate the amount of moles you multiply the volume with the concentration. So 0,256l x 0,855M = 0,218 moles.
Explanation:
Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.
- In volcanic region, it is common to see volcanic structures of different types such as calderas, strato-volcano etc. These structures are formed by the volcanic activities.
- Also, in a karst topography, we find sink holes, stalactites and stalagmites etc. due to the nature of the geologic activities going on.
- Some sedimentary rocks shows cross bedding due to the environment where they form.
So, geologic activities controls the structure found in an area
Answer:
V₂ = 30.20 L
Explanation:
Given data:
Initial volume = 45 L
Initial temperature = 298 K
Final temperature = 200 K
Final volume = ?
Solution;
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 45 L × 200 K / 298 k
V₂ = 9000 L.K / 298 K
V₂ = 30.20 L
Answer:
the symbol shows that the reaction is reversible
